I've downloaded a cs:s no-steam version. It's a cider. everything works fine, but I wanna add a material wallhack (for playing offline, since I have to add manually the sources to play Online, and I'm just too lazy), but when I try to delete the original "materials" folder to add the new one, it says that the file cannot be deleted. I also can't rename or add files, and basically, write on the application. It's definetly protected, and i'm not really sure how to disprotect. PD.: I just bought my mac a week ago, so i'm not very experienced with the OS. maybe it's easy to solve this problem and I just don't know how to. thanks in advance.
